Abstract: ABSTRACT          This invention concerns an apparatus for detecting the presence of faults in a translucent container of the kind comprising a scanning zone in which a translucent container is rotated while being repeatedly scanned by a spot beam of light in a direction parallel to the axis of rotation of the container, a light collection apparatus being arranged to receive light from the beam after passing through the container. The light collection apparatus comprises a rectangular matrix of photosensitive devices disposed behind a light-diffusing screen upon whose front surface the light from the scanning beam falls after passing through the container. A rectangular grid of thin white walls is sandwiched between the screen and the photosensitive devices so as to define a plurality of boxes with a respective device being located at the rear of each box.  The grid thus effectively divides the screen into a large number of elemental areas and provides that each device receives light substantially only from a respective elemental area of the screen.  This invention permits the detection of certain non-occlusive refraction faults in the translucent container by selective examination of the device outputs, as well as the detection of occlusive faults by measurement of the total light falling on the screen.

Abstract: ABSTRACT OF THE DISCLOSURE         Automatic braking apparatus for controlling the speed of a vehicle travelling downwardly on an inclined slope.          The apparatus comprises a wheel housing, a pair of specially designed wheels mounted in the housing for combined rotary and axial motion, and a rail engageable between the wheels and movable longitudinally relative thereto.  The wheels have tapered camming surfaces which confront one another and annular braking surfaces facing outwardly in juxtaposition with respect to pads of friction material carried by the housing.          A load applied between the rail and the wheels forces the wheels axially outward into engagement with the friction pads to retard rotation of the wheels and thereby to limit the relative velocity between the rail and the wheel housing.  In one embodiment, the wheel housing is carried by a pallet and the rail is mounted stationary.  Wedge means is provided at the lower end of the rail for engaging between the wheels relatively close to their rotational axis to arrest motion of the pallet.  In another embodiment, the wheel housing mounts a plurality of the special wheels, and the rail depends from the pallet and engages between the wheels.  In this embodiment, motion of the pallet is arrested by causing the rail to enter a zone where the wheels are spaced further apart.  Other embodiments are also disclosed.

Abstract: Abstract Method and apparatus for serial data transmission wherein each data word has a fixed bit length and each bit is transmitted during a fixed dur-ation data period following a sync pulse.  The sync pulse for each data word has a duration equal to a data period.  Each data bit pulse has a duration less than a data period.  The method and apparatus is particularly suitable for remote control systems for use with television receivers.  Apparatus for receiving serial digital coded signals and converting them to parallel digital coded signals is described.  The received signals are of the form having a predetermined number of equal time data periods, the first data period con-taining a sync pulse having a duration equal to a data period and at least one subsequent data period containing a data pulse; each data pulse is shorter than a data period.  The apparatus comprises a digital clock producing two clock signals which are identical but displaced mutually by 90 electrical degrees.  A digital counter produces enabling signals in response to the first clock signal, each enabling signal lasting one full cycle of the first clock signal.  A detector senses a received sync pulse and enables the first and second clock signals and the counter upon the termination of the received sync pulse.  A gating device sequentially gates the received signal to various outputs during successive data periods of the received signal, the gating device being controlled by the enabling signals from the counter and the second clock signal.

Abstract: ABSTRACT   A wet deasher for boilers in which ash is discharged into quench water carried in a trough beneath the boiler and in which conveyor equipment discharges ash from the trough.  Quench water is circulated through the trough between a feed and an overflow with a separator means adjacent the overflow for preventing large particles of ash from being carried over in the quench water.  The overflow passes to a pump feeder tank with heat exchanger means arranged in the tank for cooling the water and with an inclined bottom to the tank leading to the outlet for the circulating pump.  Baffles constrain the flow of quench water through the tank so that it is swept successively through defined sections of the heat exchanger.  Means are provided for ensuring that any ash happening to settle out in the feeder tank is carried back to the pump.
